Frequently Asked Questions
What is the maximum CPU clock frequency of the PIC16C73B-04/SO?
The PIC16C73B-04/SO operates at a maximum clock frequency of 4 MHz, delivering up to 1 MIPS of instruction throughput, which is sufficient for basic sensor polling, serial communications, and simple control loops in embedded systems.
Does the PIC16C73B-04/SO include an analog-to-digital converter, and what does that mean for sensor designs?
Yes, the PIC16C73B-04/SO includes an integrated ADC, allowing designers to directly sample analog signals from temperature sensors, potentiometers, or pressure transducers without adding a separate conversion chip, reducing BOM cost and board space.
How does the 28-pin SOIC package of PIC16C73B-04/SO compare to a DIP package for production assembly?
The 28-pin SOIC (MS-013) package of PIC16C73B-04/SO uses a 0.300-inch body width and standard 1.27 mm lead pitch compatible with SMT pick-and-place assembly, offering a smaller PCB footprint than a 28-pin DIP while still providing 28 accessible pins.
Is the PIC16C73B-04/SO a good fit for legacy system maintenance given its 1990 introduction date?
The PIC16C73B-04/SO was introduced in 1990 and carries a YTEOL indicator of 3, meaning it is approaching end-of-life. For new designs, Microchip recommends migrating to current PIC16 or PIC18 family devices with higher clock rates and enhanced peripherals.
